If there ever was a character that was noticeably absent in the Marvel Cinematic Universe, it’s the space dog Cosmo. After being lost in space, the pupper that loves saying “comrade” somehow ended up in The Collector’s collection but was never seen again since Guardians of the Galaxy in 2014. Luckily, we learned that Maria Bakalova will take on the role in Guardians of the Galaxy Vol. 3 and it seems she’ll also appear in the Holiday Special.
The first trailer has dropped and while we don’t hear Bakalova voice the character, we do get the confirmation that Cosmo has a role of some kind in the Holiday Special. It likely may be just a minor role and she could appear in the party that is hinted at, but it would be fun to see how this Guardians of the Galaxy midquel potentially sets up the threequel in this franchise.
We don’t know quite yet if Cosmo has taken on the same role she did in the comics as the new de facto leader of Knowhere. Perhaps that’s where they have the party with what seems to be the Ravagers, but we’ll have to see how she factors into this story. Either way, it’s great to see the galactic corner of the MCU finally explore her character and hopefully set up more appearances in the future. If there was something missing in this franchise, it’s a telekinetic dog.
